Bacterium discovery helps to solve the puzzle of what factors limit cell size

On sunken leaves in the waters of a Caribbean mangrove swamp, researchers discovered a bacterium that challenges the prevailing view of bacterial cell size; counter to the notion that microbes are only visible with a microscope, this one – named Thiomargarita magnifica – is larger than all other known giant bacteria by ~50-fold, and can be seen by the naked eye, the study's authors say.

Study unravels how lysosomal damage response pathways prevent kidney injury

Human cells need to work like well-oiled machines to keep our bodies running as they should. Waste products such as misfolded proteins, damaged cellular components, and carbohydrates get in the way and must be quickly disposed of.

Researchers report how Zika proteins hijack host cells

Most people infected with Zika never show symptoms. But the virus sometimes causes severe disability -- from microcephaly in babies to weakness or partial paralysis in adults -- and there is no treatment.
